.To all az lw-riie't-may c'oncern: v "Be it known thatwe, CHARLES S.

Fig.

spring seats" and brake hangerbrackets that are'carried by theequalize'rjbars' of the The principal object of'onr invention is,

'- to sup ort' the brakes hoe at a fixed elevation withfrespect :to thetops of the track rails so that said brake shoes, when applied -.,tothe" peripheries of. the ear wheels, will always engage the same at thesame relative .points,re ardles'sof the'variationof the eleration-o thevertically movable. parts of .t-he truck framea-an'd to this e'nd wehave provided a. construction wherein the brake hanger brackets areattached through the spring seats directly to the equalizer bars thatare arranged between the journal boxes at the sides of the trucks, andwhich equalizer bars maintain a fixed horizontal plane with respect tothe tops of the track rails.

It has heretofore been the general practice to hang the brake beams andbrake shoes from the truck frame, but such arrangement is. not desirableowing to the fact that Patented Apr. 29,1913. I

the height at which the truck frame is carried varies to a considerabledegree,-dependent upon the weight of the car body and its load and thevariations in the elevation of the track.

The equalizer bars of a truck frame are the logical and most desirablepoints for the attachment of the brake hanger brackets by reason oftheir proximity to the wheels of the truck, and by reason of their fixedrela tion in elevation to the tread surfaces of the track rails, and wepropose to'combine the brake hanger brackets and the spring seats thatare located on the equalizer bars, there by providing a simple, strongand rigid construction which can be readily applied to the equalizerbars, and which will support the brake; hangers in proper. position withrep fi ct' to the truck wheels. e

To the above purposes our invention consists in certain novel featuresof construction and arrangement of parts hereinafter more fullydescribed and claimed.

- Referring to the drawings and particularly to the constructionillustrated in Figs.

-l and 2, 1O designates the wheel pieces of a truck frame, 11 theparallel equalizer bars,

13 the pedestals and 14 the journal boxes positioned between thepedestals and upon The lower spring seats, as contemplated 9O which theends of the equalizer bars engage; a

by our invention, are each composed of a horizontally disposed plate 15,and formed integral therewith isa pair of depending ears or brackets 16which straddle the upper port-ions of the equalizer bars 11, and passingthrough these cars or brackets and said equalizer bars are horizontallydisposed bolts o'r-rivets 17 Located on these bolts upper end of thecorresponding brake hanger llnk 21 is pivotally connected. Carried bythe lower end of. this,link is an ordinary brake shoe carrying head 22which is adapted to engagethe periphery of the adjacent wheel.

i In the modified construction'illustrated in Fig. 3 the spring seats oneach equalizer bar are joined to'each other by a connecting rod; 23,which latter lies immediately above the: equalizerbar, and where suchconstruction: is utilized, the fastening means comprising the rivets orbolts-17 can be dispensed with and'the conneeriingrod 23 holds thespring seats against tilting movement upon the equalizer bars.

In the modified construction shown in hanger bracket is shown positionedon a single equalizerbar, and the bracket is provided with a lug 19 towhich is attached one end of a rod 19" that extends across the .carltruck, and connects to the corresponding bracket on the opposite side ofthe truck frame. If desired this arrangement of con-i necting theoppositely disposedpairs of brackets can be combined with the connectingrods 23, and thus all four of the combined spring seats and brackets canbe united by tierods. In Fig. 6 I have illustrated a construction'wherein the combined spring seat and bracket is formed integral withthe equalizer bar.

By our improved construction the lower;- spring seat and brake hangerbracktare; formed in a sin le piece, which can be read-- ily combinedwith the equalizer bar, and as said equalizer bar'always maintains thesame; elevation with respect to the tread surfaces: of the track rails,the brake shoes are conse-I quently held at fixed elevations withrespect to the truck wheels, and therefore the brakeshoes will besuspended and held in roper relation to the truck wheels, regard ess ofthe varying elevation of the truck frame.

It will be readily understood that minor changes in the size, form andconstructionof thevar ms parts of our improved car truck; can be madeand substituted for thoseherein shown and described without departingfrom' the spirit of our invention, the scope of which is set forth theappended claims.
